Climb.org.au guide is a about as good a guide as you will find. I think the canberra climbing club also hosts a PDF copy of the original early 90s print guide. Generally bungonia can get hot but shady side is ok. Strangeness is the pic of the routes there. Doubles fairly useful - a 7. Especially since you'll need two ropes to rap off anyway.

If its 40 and not a puff of breeze it goes without saying you're stuffed.

As Neil mentioned north wall. This includes chicken wall. Polenta pumper wall cops a fair bit of shade. Wst pitch of siblings area can make a cool wind tunnel, nearly always in the shade. That first pitch is a good one btw. Iron curtain to supergiant in the mornimg, rap off when the sun hits.
